MKS Gen Stepper Compatibility

Fan Wiring Connection

The MKS Gen 1.4 comes with limited connections for your 3d printer’s extruder fans, board cooling fans and part cooling fans. This connection is for your 3d printers cooling fan as it kicks on after your first layer has been completed during the print.

But what about the Extruder Fans?

You might be asking yourself how to connect the extruder fans, at least that is what happened to me. I reached out to King at makerbase and he suggested connecting them to the secondary input voltage connector. But then I thought well that would mean the fans would always be on which is not ideal or power friendly.

So I searched for a better way and I found that you can use a relay or even better a MOSFET Driver Module!

These little guys make is easy to add low amp hardware and control them with the signal pin. Simply wire these to the secondary power input on the board, wire up the fans and then connect the signal pin to a free digital pin. Then just modify your firmware configuration to activate the pin for the extruder fan power. These support up to 24v which makes them a great and affordable choice.

Smart Controllers (Screens)

MKS Gen 1.4 supports many Smart Controllers and Touch Screens. They have their own line of touch screens which are pretty nice.
